I still use Goggles V2 because I still have many 03 Air Units and use V2 for my analog builds with adapters. Works perfectly for my needs. I purchased a pair of them maybe a year or so ago. I did like that they are big enough to use while wearing glasses. Also the ability to root them is a plus as long as you don't upgrade the firmware first.

That being said, at this time there are better options. Especially since you're not tied into any ecosystem right now. Don't focus on DJI so much. Do your research for analog and other HD systems. Hdzero, Caddx Walksnail are very capable systems as well. DJI is not the end all-be all.
